What happened : The British health authorities, on Wednesday, warned that anyone who has a prior underlying health history of allergic reactions should not get the Pfizer Covid-19 vaccine, at least for the time being. This statement was made after some of the National Health Service (NHS) staff, who received the vaccine, suffered from an allergic reaction. Pfizer confirmed that the Medicines and Healthcare Products Regulatory Agency (MHRA) had informed it of the allergic reactions, but also said that during phase 3 trials of more than 40,000 people, the vaccine was ” generally well-tolerated with no serious concern”. The background: Thousands of Britons became the first in the West to have been administered an approved Covid-19 vaccine shot, as the biggest vaccination drive kicked off in the UK. The vaccine, administered in two doses 21 days apart, is believed to help boost immunity and prevent opportunistic infections and post Covid complications.
