However, in July 1999, the Public Health Service (PHS) agencies, the American Academy of Pediatrics (AAP), and vaccine manufacturers agreed to reduce or eliminate thimerosal in vaccines as a precautionary measure. According to the CDC, no harmful effects have been reported from the amount of thimerosal used in vaccines, other than expected minor reactions like redness and swelling at the injection site.

Recombinant Newcastle disease virus (rNDV) strain LaSota expressing HA protein vaccine has shown promising results against HPAIV; however, its replication is restricted only to the respiratory tract. Conjugate vaccines use parts from the outer antigen coat of the bacteria or virus, which are not strong enough to cause illness or generate an immune response in the body. This production technology has some drawbacks including the fact that growth in eggs can cause mutations in the vaccine viruses that can impact how well the vaccines work.
