There may be some drawbacks for the recombinant vaccine. However, the examples are that reinforcement shots may be required over time.Examples of recombinant vaccines are pneumococcal vaccines and vaccines for meningococcal diseases . . for the animals.Adenovirus-based vaccines can also present some problems that adenovirus is so common that the vaccine may not be as effective when the doses of the amplifier are shown, or that some people already have immunity to the virus used in the vaccine.
