Caller was concerned about the fact that he was hearing quite a few people wind up getting the virus even though they have been fully vaccinated with the COVID vaccine. His cousin went into an assisted living facility 2 months ago, and she has been previously vaccinated. He has been fully vaccinated as well and three of the people got covid at her assisted living that have been fully vaccinated. He was wondering if Pfizer was started to get any more information about the virus and the vaccine. He knows the vaccine was not 100% effective and question was Pfizer getting an uptick in people that are getting the virus after vaccination. Caller do not have information on the three people at the assisted living. He was just concerned about himself and worried about some of the information out there not being accurate. Just like some places say no mask, and some say mask. He got vaccinated back in Mar2021. He does not know how much longer he has to live and would just like more in-formation. As of 21Jul2021, Caller asked about a potential booster dose from Pfizer for covid-19. He said that there again if it became available as a older man would be willing to take in other words to have further protection. Response was provided as part of Pfizers and BioNTechs continued efforts to stay ahead of the virus causing COVID-19 and circulating mutations, the companies provided an update on booster dosing on 9July2021. Please note that the use of a 3rd or booster dose is not recommended or authorized, and Pfizer does not suggest the use of the vaccine in any manner other than as described in the authorized product monograph. Initial data from the ongoing study of booster doses demonstrated a consistent tolerability profile and high neutralization titres against the wildtype virus (the naturally occurring non-mutated virus) and the Beta variant. It is thought that the effects seen against the Beta variant may also be seen in the Delta variant. We are doing studies to confirm this." Also referenced the press release, Pfizer and BioNTech Provide Update on Booster Program in Light of the Delta-Variant, "anticipate the clinical studies to begin in August, subject to regulatory approvals". Referred to HCP for risk/benefit of receiving this dose if/when available. The patient underwent lab tests and procedures which included COVID-19: positive on unspecified date. The clinical outcome of the events was unknown.  Information on the lot/batch number has been requested.
