London. There have been studies in the UK on people reporting the effects of Pfizer after the covid vaccine. It has been revealed that the symptoms observed in most people after the vaccine is not serious. According to the findings released by the Kovid Symptoms Study App on Thursday, most symptoms occur in the 2 days immediately after vaccination. Headache, fatigue and chills or dizziness are also most common among them. Researchers found that people who had previously been exposed to coronaviruses were more likely to experience such experiences after vaccination.

The team analyzed reports of about 40,000 people. These are the people who were vaccinated in December. Of these, 23,308 people were those who had received one dose and 12,444 people who had received both doses. The study revealed that about 4 out of 10 people experienced pain or swelling in their shoulder a day or two after taking the first dose.

Let us know that the Kovid Symptoms Study has been created by doctors and scientists in association with ZOE, a health science company. The study was led by Professor Tim Spector of King’s College London. “Our ZOE app data is showing signs of survival after 40,000 days among 40,000 health care workers,” Spector tweeted.

In the UK, the Pfizer / BioNtech Kovid-19 vaccine began on 8 December. Since then, lakhs of people have been vaccinated here. This includes the elderly, health care workers and NHS staff members.

Researchers also compared the effects of vaccination between those who had Kovid-19 and those who had not received the infection. Analysis showed that one-third of people who had a kovid infection showed at least one symptom within 7 days of the vaccine. While people who did not get corona infection, only 1 in 5 people have had any symptoms after getting vaccinated. (IANS)
