With prominent vaccine developers rushing to offer a shot against the COVID-19 pandemic, the UK’s Medicines and Healthcare products Regulatory Agency has warned that people with a history of significant allergic reactions should not have the Pfizer/BioNTech Covid dose.
The warning came after two National Health Service workers in that country had allergic reactions on Tuesday (Dec 8).

The advice applies to those who have had reactions to medicines, food or vaccines, the regulator said. The two people had a reaction shortly after having the new jab, had treatment and are both fine now.
Several thousand people were vaccinated on Tuesday in hospital clinics on the first day of the UK rollout of the new COVID jab.
The advice also states that vaccines “should only be carried out in facilities where resuscitation measures are available.” “We are fully investigating the two reports that have been reported to us as a matter of priority,” an MHRA spokesperson said.
Pfizer said in a statement that it had been advised by the UK regulator of “two yellow card reports that may be associated with allergic reaction” due to administration of the vaccine.

“In the pivotal phase-3 clinical trial, this vaccine was generally well tolerated with no serious safety concerns reported by the independent Data Monitoring Committee. The trial has enrolled over 44,000 participants to date, over 42,000 of whom have received a second vaccination,” said Pfizer.
The US Food and Drug Administration (FDA) has said the Pfizer/BioNTech trial data hinted that there were potentially slightly more adverse responses thought to be allergic reactions among the vaccine group compared with the placebo group, at 0.63% compared with 0.51%.

The vaccine efficacy will be determined 14 days post the second dose. Covaxin has been designed to be efficacious when subjects receive both doses,” Bharat Biotech, whose first dose was given to Vij, was quoted as saying.
“The phase-3 trials are double-blinded and randomized, where 50 per cent of subjects receive vaccine and 50 per cent of subjects receive placebo,” said Bharat Biotech.
