Strong hangover is one of the effects reported by vaccine volunteers


Volunteers who tested the covid-19 vaccine developed by Pfizer in partnership with the German company BioNTech reported experiencing a side effect similar to a strong hangover, which disappeared quickly, according to the Daily Mail.

Altogether, 43,500 people are part of the study, which divides participants into two groups: those who receive the actual vaccine and those who receive a placebo (a substance without effect). Although, these people are not informed about the group of which they are part, due to the side effects, they come to know that they got the vaccine.

In addition to the hangover, some volunteers also reported headaches and muscle aches, effects commonly reported in studies with other vaccines against covid-19.

According to two study participants, aged 45 to 44, both developed symptoms similar to those they had when they got the flu vaccine. One said the symptoms were still severe after receiving the second dose.

The Pfizer and BioNTech vaccine had a preliminary analysis released last week, which found it to be 90% effective in preventing disease caused by the new coronavirus.

During the announcement of efficacy, pharmacists said that no serious adverse reaction or serious issue with the safety of the immunizer had been identified.

“We must be more optimistic about the effect of immunization, which can last at least a year,” explained the director of BioNTech, Ugur Sahin.

The study is still ongoing, but the companies plan to apply for authorization for emergency use of the vaccine in the United States as early as next month.

The projection of the companies is to produce about 100 million this year. Brazil does not yet have an agreement with the pharmaceutical company to receive doses of the vaccine, but a meeting between Brazilian authorities and representatives of the laboratory is scheduled for the next few days.
