Pfizer and U.S. health officials met Monday to discuss whether or not a coronavirus booster vaccine is necessary.

The meeting comes amid a public dispute last week in which the two sides publicly announced conflicting information.

Pfizer says it was beginning to see waning immunity from its double dose vaccine and would be seeking authorization for a booster dose.

However, the FDA and CDC issued a joint statement saying in part, “Americans who have been fully vaccinated do not need a booster shot at this time. FDA, CDC, and NIH are engaged in a science-based, rigorous process to consider whether or when a booster might be necessary.”

Good Samaritan Hospital Dr. Uzma Syed tells News 12 there are two main reasons for a booster shot.

“One would be if you have a variant that emerges that evades all of the current vaccines which we don't have,” says Dr. Syed. “And the second would be if you have significant waning immunity where the vaccinated population that you have. The majority of them are getting re-infected or have severe disease and ending up hospitalized and that's something that we don't have either.”

According to health officials, the focus should still be vaccinating those who aren’t vaccinated – not concern over the Delta variant.

Ronkonkoma resident Joyce Saccoccio says she’s unsure if she’ll take the booster vaccine. “I feel better that I took It, I definitely do. I just don't know if I want to do the booster.”
