No Adverse Side Effects Of Covid-19 Vaccine: Study

Hyderabad : Vaccines administered in the city so far for prevention of Covid-19 did not show any major adverse reaction. All the side-effects reported after Covid-19 vaccination are in terms of the manufacturer’s data and the doses administered are safe, says a research study conducted by a city-based medical college and hospital.

Most of the people, who reported minor side-effects after vaccination, are in the age group of 18 to 28 years. Pain in injection site was reported in 45 per cent and fever in 31 per cent of the vaccinated population. But all side-effects were normal and subsided soon afterwards, the study revealed.

“The overall results found the occurrence of side-effects are in the terms of the manufacturer’s data and it has been noticed in young age. The presence of local side-effects should not hamper the vaccination drive to protect against the pandemic. This study imparts the confidence for taking vaccination and further studies are required to strengthen the will of public to boost confidence to take vaccine in the present vaccination drive,” said the researchers from the Kamineni Academy of Medical Sciences and Research Centre, Hyderabad.

“As many as 1,364 healthcare workers participated in the study. Majority of the symptoms following immunization were highest in age group of 18-28 years. Reported symptoms were pain at the site of injection in 45.4%, fever in 31%, body pains in 23.3%, headache in 13.9%, tiredness in 10.4%, swelling at the site of injection in 2.9%, dizziness in 2.2%, redness at the site of injection in 1.8%, joint pains in 1.7%, rash in 0.4%, breathlessness in 0.2%,” the study said.
