A single dose of Pfizer vaccine may be less effective than your doctor had told you, warned Tsar COVID-19 in Israel.
Nachman Ash – the Israeli equivalent of Dr. Anthony Fauci – said the protection provided by the first dose was “less effective than I thought,” Army Radio reported.
“Many people were infected between the first and second injection of the vaccine,” said Ash, adding that the protective effect appears to be less than [the data] presented by Pfizer. ”
The pharmaceutical giant claimed that studies show that it is about 52 percent effective about 12 days after receiving the first blow, the BBC reported.
But this level of protection increases to 95% about two weeks after the second dose.
It is unclear how effective the shooting was for the more than 2 million Israelis who have already received the first dose.
Questions have been raised about the vaccine’s performance after health officials announced 10,000 new cases on Monday, the largest since the pandemic began.
Experts have repeatedly warned that a dose of vaccine does not provide full immunity and that social distancing measures will be needed to control the pandemic.
