Delayed large local reaction to the adenovirus-vectored (ChAdOx1) vaccine

Clinical Assessment of a Novel Recombinant Simian Adenovirus ChAdOx1 as a Vectored Vaccine Expressing Conserved Influenza A Antigens

Adenoviruses are potent vectors for inducing and boosting cellular immunity to encoded recombinant antigens. However, the widespread seroprevalence of neutralizing antibodies to common human adenovirus serotypes limits their use. Simian adenoviruses do not suffer from the same drawbacks. We have constructed a replication-deficient chimpanzee adenovirus-vectored vaccine expressing the conserved ...

Aerosolized adenovirus-vectored vaccine as an alternative vaccine delivery method

Conventional parenteral injection of vaccines is limited in its ability to induce locally-produced immune responses in the respiratory tract, and has logistical disadvantages in widespread vaccine administration. Recent studies suggest that intranasal delivery or vaccination in the respiratory tract with recombinant viral vectors can enhance immunogenicity and protection against respiratory dis...

Harnessing the Potential of Adenovirus Vectored Vaccines

Unusual delayed reaction after H1N1 vaccine.

We reported a case of allergic contact dermatitis three weeks after the H1N1 vaccine, probably involving thimerosal additive. Patients should be aware of this possible unusual delayed reaction.

An Atypical Local Vesicular Reaction to the Yellow Fever Vaccine

Yellow fever vaccine is a live attenuated viral inoculation indicated for patients traveling to endemic areas. The vaccine is generally well tolerated with minimal adverse effects. Typical side effects include malaise, pain at the injection site, and, albeit rarely, immediate hypersensitivity reactions. We present a case of a rare adverse reaction to yellow fever vaccine in which a patient deve...
