1.   ORGANIZATION AND BASIS OF PRESENTATION

     ORGANIZATION

     Vical was incorporated in April 1987 and has devoted substantially all of
     its resources since that time to its research and development programs.
     The Company is currently focusing its resources on the development of its
     direct gene transfer and related technologies.

     BASIS OF PRESENTATION

     The information contained herein has been prepared in accordance with
     instructions for Form 10-Q.  The information at June 30, 1998, and for the
     three-month and six-month periods ended June 30, 1998 and 1997, is
     unaudited.  In the opinion of management, the information reflects all
     adjustments necessary to make the results of operations for the interim
     periods a fair statement of such operations.  All such adjustments are of
     a normal recurring nature.  Interim results are not necessarily indicative
     of results for a full year.  The preparation of financial statements in
     conformity with generally accepted accounting principles requires
     management to make estimates and assumptions that affect the reported
     amounts of assets and liabilities and disclosures of contingent assets and
     liabilities at the date of the financial statements and the reported
     amounts of revenues and expenses during the reporting period.  Actual
     results could differ from those estimates.  For a presentation including
     all disclosures required by generally accepted accounting principles,
     these financial statements should be read in conjunction with the audited
     financial statements for the year ended December 31, 1997, included in the
     Vical Incorporated Form 10-K filed with the Securities and Exchange
     Commission.

2.   NET LOSS PER SHARE

     Net loss per share (basic and diluted) for the three-month and six-month
     periods ended June 30, 1998 and 1997, has been computed using the weighted
     average number of common shares outstanding during the respective periods.
     Diluted loss per share does not include any assumed exercise of stock
     options as the effect would be antidilutive.

3.   COMPREHENSIVE INCOME

     The Company implemented Statement of Financial Accounting Standards No.
     130 "Comprehensive Income" effective January 1, 1998.  This statement
     requires that all items that are required to be recognized under
     accounting standards as components of comprehensive income be reported in
     a financial statement that is displayed with the same prominence as other
     financial statements.  Accordingly, in addition to reporting net income
     (loss) under the current rules, the Company is required to display the
     impact of any unrealized gain or loss on marketable securities as a
     component of comprehensive income and to display an amount representing
     total comprehensive income for each period presented.  In interim
     financial results, this information is allowed to be presented in the
     notes to the financial statements.  For the three-month periods ended June
     30, 1998 and 1997, other comprehensive (loss) income was ($19,061) and
     $127,426, respectively, and total comprehensive loss was $2,953,779 and
     $2,139,522, respectively.  For the six-month periods ended June 30, 1998
     and 1997, other comprehensive (loss) income was ($19,756) and $9,990,
     respectively, and total comprehensive loss was $3,675,572 and $4,259,166,
     respectively.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

OVERVIEW

Vical was incorporated in April 1987 and has devoted substantially all of its 
resources since that time to its research and development programs.  The 
Company is focusing its resources on the development of its direct gene 
transfer and related technologies.  Currently, the Company is developing its 
ALLOVECTIN-7, LEUVECTIN and VAXID cancer product candidates internally, while 
developing vaccine product candidates for infectious diseases primarily in 
collaboration with corporate partners Merck & Co., Inc. ("Merck") and Pasteur 
Merieux Connaught ("PMC").  In February 1998, the Company and Centocor, Inc. 
entered into a license agreement allowing Centocor, Inc. to use Vical's naked 
DNA technology to develop and market certain gene-based vaccines for the 
potential treatment of certain types of cancer.  To date, the Company has not 
received revenues from the sale of products.  The Company expects to incur 
substantial operating losses for at least the next several years, due 
primarily to expansion of its research and development programs and the cost 
of preclinical studies and clinical trials.  As of June 30, 1998, the 
Company's accumulated deficit was approximately $33.9 million.

Vical has formulated ALLOVECTIN-7, a complex containing the gene encoding a 
particular human histocompatibility antigen, HLA-B7, and a lipid material to 
facilitate gene uptake.  After direct injection of ALLOVECTIN-7 into a tumor, 
the Company believes that the HLA-B7 gene will cause the tumor cells to 
produce the HLA-B7 antigen.  This gene expression may then trigger a potent 
cellular immune response against the tumor cells.

In May 1998, the Company initiated registration-supportive expanded Phase II 
and Phase III multi-center clinical trials in certain patients with 
metastatic melanoma.  Either or both of the pivotal trials could support 
initial product registration if endpoints are achieved. The FDA has reviewed 
data from previous studies and has confirmed acceptability of the designs, 
endpoints, and analysis plans for both new trials.  The open-label, 
multi-center Phase II trial is designed to confirm the efficacy of 
ALLOVECTIN-7 in the defined patient population which appeared to benefit most 
in earlier Phase II trials. Enrollment will be open to patients with 
metastatic (spread beyond the initial site), refractory (unresponsive to 
standard therapy), Stage III or IV disease that has not yet spread to 
multiple internal organs.  Up to 70 advanced melanoma patients will be 
enrolled at approximately 15 leading cancer treatment centers throughout 
North America.

The objective is a clinical partial or complete response in at least 15 
percent of the evaluable patients, persisting with a median duration of at 
least four months. The open-label, multi-center, randomized, controlled Phase 
III trial is designed to determine the efficacy of ALLOVECTIN-7 when combined 
with standard chemotherapy in patients with unresectable, metastatic melanoma 
not previously treated with chemotherapy.  In prior trials, ALLOVECTIN-7 was 
used only after standard therapies had failed.  In the new trial, patients 
may be enrolled upon diagnosis or upon progression to Stage III or Stage IV 
disease when surgery or radiation therapy are usually no longer curative.  
Because ALLOVECTIN-7 is intended to trigger an immune response against tumor 
cells, the Company believes the treatment may be more effective in patients 
whose immune systems have not been compromised.

Approximately 140 patients per group, randomized by sex, age, and extent of 
disease spread, will be enrolled into a chemotherapy-plus-ALLOVECTIN-7 
experimental group or a chemotherapy-only control group.  The objective is a 
greater relative clinical benefit for the experimental group than for the 
control group.  Acceptable endpoints are either an improvement in the median 
time to disease progression, or in the rate of objective clinical responses.

                                        7



Results from another Phase I/II trial of ALLOVECTIN-7 suggested potential 
efficacy in certain patients with unresectable head and neck cancer.  A 
multi-center Phase II trial with ALLOVECTIN-7 in approximately 25 patients 
with unresectable head and neck cancer began in September 1997. Preliminary 
results released in May 1998 for 23 evaluable patients in a company-sponsored 
multi-center Phase II trial yielded one clinical complete response lasting 4 
months and continuing, and 10 patients with stable disease after 2 to 4 
months and continuing.

Vical is developing its second gene-based product candidate, LEUVECTIN, also 
intended for direct injection into tumor lesions of cancer patients.  
LEUVECTIN contains a gene that encodes the potent immunostimulator IL-2 and a 
lipid material to facilitate gene uptake.  The Company expects that 
LEUVECTIN, when injected into tumors, will cause the malignant cells to 
produce and secrete IL-2 in the vicinity of the tumor, stimulating the 
patient's immune system to attack and destroy tumor cells.  Because LEUVECTIN 
is designed to deliver IL-2 only at the site of tumor lesions, the Company 
believes that it may provide similar efficacy with fewer side effects than 
systemic IL-2 therapy.

Phase I/II clinical trials testing the safety of LEUVECTIN at varying dosage 
levels were completed in patients with advanced melanoma, renal cell 
carcinoma, and soft-tissue sarcoma.  The Phase I/II results presented in May 
1998 indicated that of the 14 evaluable patients in the renal cell carcinoma 
trial, two patients achieved clinical partial responses persisting for 13 to 
14 months and continuing, and two achieved stable disease, yielding a total 
of four out of 14 evaluable patients (29 percent) deriving clinical benefit 
from treatment. Among 16 evaluable patients in the melanoma trial, one 
achieved a clinical partial response persisting for 11 months and continuing, 
and three achieved stable disease.  Among 15 evaluable patients in the 
sarcoma trial, six patients achieved stable disease.  The results of these 
trials indicated that the treatment is safe and well-tolerated, with no 
serious treatment-related adverse events reported.  Responses appeared to be 
dose-related, with all clinical responses occurring in the two highest dosing 
groups.  In May 1998 the Company initiated a multicenter Phase II clinical 
trial in patients with metastatic renal cell carcinoma. The open-label, 
multi-center Phase II trial is designed to evaluate the safety and efficacy 
of LEUVECTIN in up to 80 patients with metastatic kidney cancer and determine 
response rate and duration.

In June 1997, the Company initiated a Phase I/II clinical trial with 
LEUVECTIN in approximately 18 prostate cancer patients.   The trial was 
designed to test the safety and efficacy of LEUVECTIN as a potential therapy 
for patients with tumors apparently confined to the prostate capsule, but 
with a high likelihood of metastatic disease recurrence.  Treatment with 
LEUVECTIN was intended to stimulate a localized immune response against the 
primary tumor and a systemic immune response against any tumor cells that may 
have escaped from the capsule.

Data measurement and analysis focused on reductions in the patients' serum 
levels of prostate-specific antigen (PSA) following treatment with LEUVECTIN. 
PSA is a biochemical substance produced exclusively by prostate cancer cells 
and used as a marker to detect and monitor the disease.  Recent studies have 
confirmed that PSA levels, in combination with several other factors, are 
highly predictive of disease progression in post-surgical and post-radiation 
patients.

Results of the trial were presented in June 1998, and indicated that 
LEUVECTIN was well-tolerated and may be successful in casing targeted immune 
response against prostate cancer cells.  In five of 11 patients scheduled for 
radical prostatectomy (complete removal of the prostate gland), serum PSA 
levels decreased by at least 50 percent prior to surgery, and remained at 
undetectable levels following surgery for up to 11 months and continuing.  
Two additional patients experienced serum PSA reductions between 25 percent 
and 50 percent prior to surgery and undetectable levels following surgery for 
up to 6 months and continuing.  In four of eight patients with recurrent 
disease following radiation therapy, serum PSA levels decreased by at least 
50 percent.  Three additional patients experienced serum PSA reductions 
between 25 percent and 50 percent.

In collaboration with Dr. Ronald Levy of Stanford University Medical Center, 
the Company is developing a naked DNA anti-idiotype vaccine, VAXID, against 
low-grade non-Hodgkin's B-cell lymphoma.  VAXID is a DNA plasmid that encodes 
the patient-specific idiotype of the B-cell tumor immunoglobulin.  The 
Company believes that immunization of post-chemotherapy patients with VAXID 
could result in the elimination of residual disease and the prevention of the 
relapse of disease.  In October 1997, a Phase I/II clinical trial of VAXID 
began at the Stanford University Medical Center under the direction of Dr. 
Levy.

In July 1998, the Company announced the initiation of a Phase I/II clinical 
trial to study the safety and potential efficacy of an experimental DNA 
vaccine for patients with metastatic melanoma.  The trial is being sponsored 
by the National Cancer Institute under the direction of Dr. Steven A. 
Rosenberg, M.D., Ph.D., Chief of Surgery.  The experimental vaccine contains 
a gene which may cause cells at the injection site to produce a modified 
gp100 melanoma antigen. The antigen is expected to trigger an immune response 
against melanoma tumor cells.  In earlier studies, Dr. Rosenberg tested a 
vaccine using peptides (portions of the modified antigen) in combination 
therapy with interleukin (IL-2), a naturally occurring protein that 
stimulates the immune system.  A DNA vaccine may be more generally applicable 
and may provide advantages in manufacturing and product handling.

In July 1997, the Company and PMC began a Phase I clinical trial of an 
experimental naked DNA vaccine against the parasite that causes malaria.  The 
Company and PMC are sponsoring the trial under their Research, Collaboration 
and License Agreement.  The trial is being conducted by the U.S. Naval 
Medical Research Institute.    In April 1998, the Company released 
preliminary results from approximately 20 human participants in the trial 
which indicated that the vaccine was well-tolerated and safe.  Preliminary 
analysis of specimens from trial participants suggested a good cellular 
immune response with features that the physicians conducting the trial 
believe may be important in preventing the disease,

There can be no assurance that the Company's product candidates will prove to 
be safe and effective in clinical trials or that any commercially successful 
products will ultimately be developed by the Company.

This Form 10-Q contains, in addition to historical information, 
forward-looking statements.  When used in this discussion, the words 
"expects," "anticipated" and similar expressions are intended to identify 
forward-looking statements. Such statements are subject to certain risks and 
uncertainties, including whether the Company's product candidates will be 
shown to be safe or efficacious in clinical trials, whether the Company's 
corporate collaborations will be  successful, and whether the Company's 
product candidates will ultimately be successfully developed or receive 
necessary regulatory approvals and other matters discussed in Item 1 under 
the caption "Risk Factors" in the Company's Form 10-K for the year ended 
December 31, 1997 filed with the Securities and Exchange Commission, which 
could cause actual results to differ materially from those projected.  These 
forward-looking statements speak only as of the date hereof.  The Company 
undertakes no obligation to update these forward-looking statements to 
reflect events or circumstances after the date hereof or to reflect the 
occurrence of unanticipated events.

RESULTS OF OPERATIONS

Revenues of $560,000 were recorded for the quarter ended June 30, 1998. 
License revenue primarily consisted of payments under existing agreements 
with Cardiogene and Merial and royalty revenue of $183,000.  The Company 
received $1,000,000 from Merial for the extension of the option on five 
vaccine targets. The Company recognized as revenue $250,000 of this payment 
and reflected $750,000 as current deferred revenue in the balance sheet.  
This deferred revenue will be recognized over the remaining nine month option 
period.  The Company had revenues of $867,000 for the quarter ended June 30, 
1997, consisting of license revenue of $329,000 primarily derived from the 
PMC and Merial agreements, contract revenue of $393,000 from PMC and 
royalties amounting to $145,000.

Revenues for the six months ended June 30, 1998, were $3,292,000.  In 
addition to the revenue recognized in the second quarter, revenue for the six 
months ended June 30, 1998 also included $2,200,000 of license revenue from 
Centocor, Inc., $178,000 of license revenue from amortization of deferred 
revenue from PMC and Merial, contract revenue from PMC and royalty revenue of 
$154,000. Revenues for the six months ended June 30, 1997, were $1,993,000 
and, in addition to contract and license revenue from PMC and Merial, 
and royalty revenue, included a grant from the Department of Defense of 
$209,000.

The Company's total operating expenses for the quarter ended June 30, 1998, 
were $4,072,000 compared with $3,678,000 for the second quarter of 1997.  
Total operating expenses for the six months ended June 30, 1998, were 
$8,134,000 compared with $7,369,000 for the same period in 1997.

Research and development expenses increased to $3,058,000 for the three 
months ended June 30, 1998, from $2,797,000 for the same period in 1997.  For 
the six months ended June 30, 1998, research and development expenses were 
$6,153,000 compared with $5,591,000 in the same period of 1997.  These 
increases in research and development expenses were generally due to 
increased clinical trial costs partially offset by lower spending on external 
research.  An additional contributing factor for the increase for the six 
months ended June 30, 1998 was royalties due to the Wisconsin Alumni Research 
Foundation on the license agreement signed with Centocor, Inc. in the first 
quarter of 1998.

General and administrative expenses increased to $1,014,000 for the three 
months ended June 30, 1998, from $881,000 for the same period in 1997.  
General and administrative expenses for the six months ended June 30, 1998, 
increased to $1,981,000 from $1,777,000 for the same period in 1998.  The 
increases are attributable to increasing operational expenses within the 
administrative area in support of the Company's expanding research and 
development activities.

Investment income for the three-month and six-month periods ended June 30, 
1998, was $620,000 and $1,271,000, respectively.  Investment income for the 
three-month and six-month periods ended June 30, 1997, was $597,000 and 
$1,207,000, respectively.  The increases are primarily a result of higher 
rates of return on investments.

The net loss was $.19 per share for the three months ended June 30, 1998, 
compared with net loss per share of $.15 for the same period of 1997.  For 
the six months ended June 30, 1998, the net loss was $.23 per share compared 
with a net loss of $.28 per share  for the same period in the prior year.  
The Company expects to incur losses throughout the remainder of 1998 and to 
report a net loss per share for the year ended December 31, 1998.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception, Vical has financed its operations primarily through 
private placements of preferred and common stock, three public offerings of 
common stock and revenues from collaborative agreements.   As of June 30, 
1998, the Company had working capital of approximately $42.1 million compared 
with $44.9 million at December 31, 1997.  Cash and marketable securities 
totaled approximately $43.7 million at June 30, 1998, compared with $45.6 
million at December 31, 1997.

The Company expects to incur substantial additional research and development 
expense including continued increases in personnel costs and costs related to 
preclinical testing and clinical trials.  The Company's future capital 
requirements will depend on many factors, including continued scientific 
progress in its research and development programs, the scope and results of 
preclinical testing and clinical trials, the time and costs involved in 
obtaining regulatory approvals, the costs involved in filing, prosecuting and 
enforcing patent claims, competing technological and market developments, the 
cost of manufacturing and scale-up, and commercialization activities and 
arrangements.  The Company intends to seek additional funding through 
research and development relationships with suitable potential corporate 
collaborators or through public or private financing. Additional funding may 
not be available on favorable terms or at all.

                                        10



If additional funding is not available, Vical anticipates that its available 
cash and existing sources of funding will be adequate to satisfy its 
operating needs through 1999.

YEAR 2000 ISSUES

The Company is currently developing a plan to insure that its system and 
software infrastructure are Year 2000 compliant.  Key financial information 
and operational systems will be assessed and plans will be developed to 
address required systems modifications.  Given the relatively small size of 
the Company's systems and the predominantly new hardware, software and 
operating systems, management does not anticipate any significant delays in 
becoming Year 2000 compliant.  However, the Company is unable to control 
whether its current and future strategic partners systems are Year 2000 
compliant.  To the extent that strategic partners would be unable to procure 
clinical materials or services provided by the Company, or otherwise manage 
their clinical trials and research and development activities, or to pay 
invoices owed to the Company, or to the extent that suppliers are unable to 
manufacture and ship materials or provide requested contract services, the 
Company's operations could be affected.  However, at this time management has 
no reason to believe that Year 2000 changes will have a material impact on 
the Company's business, financial condition or results of operations.
