Why Are So Many People Who Have Had a Pfizer Vaccine Getting Infected?
Pfizer is a two-dose vaccination regime with data showing a 33% protection rate from getting infected after the first dose and 80% protection from hospitalisation. Once a second dose is received, protection against hospitalisation from the Delta strain increases to 94%.
Due to the lower protection rate after the first vaccine, the prevalence of the delta variant and that many people may be standing in queues as well as possibly lowering their adherence to protection guidelines, we have unfortunately seen many people infected in the first couple of weeks after their first vaccine.
It is important to remember, that the Pfizer vaccine only provides full immunity two weeks after the second dose.
