In the midst of the novel corona virus epidemic, the Pfizer vaccine is very much in discussion these days. Now the news related to the side effects of this potential vaccine is also coming out. According to a report in the Daily Mail, many volunteers say that they felt a deep hangover after taking the first dose. Volunteers have also complained of headaches, fever, muscle aches.

A 45-year-old volunteer said that from the first dose, he experienced “headaches, fever, and full body pain” as side effects, which became more severe after the second dose. At the same time, a 44-year-old volunteer said that he felt a deep hangover from the Pfizer vaccine, but the symptoms soon went away.

It has been reported in the report that more than 43,500 people in 6 countries took part in the phase 3 trials of this vaccine candidate.

British Prime Minister warns

US-based pharmaceutical major Pfizer and German biotech firm BioNotech recently said that their potential vaccine was found to be 90 percent effective in fresh clinical trials.

After this, British Prime Minister Boris Johnson cautiously welcomed the results of this vaccine candidate and warned people not to rely on this news as a solution because it is still “in a very early stage”.

Johnson said, “The Pfizer / Bioentech vaccine has been tested on more than 40,000 volunteers and interim results indicate that it is 90 percent effective in protecting people from the virus.” But we have not yet seen the complete safety data, and these results also need to be reviewed by experts. ” He said that it is important that we do not overdo things.
