New Delhi: Recently, after a disclosure by British pharmaceutical company AstraZeneca, there is a lot of discussion about Corona vaccine. AstraZeneca has admitted in court that Covishield can cause thrombosis with thrombocytopenia syndrome (TTS) in rare cases. This can cause blood clots to form and reduce platelet count. In severe cases it can also cause stroke and heart attack. After this revelation, discussion started in India also. Serum Institute of India has made the Covishield vaccine in India using the same formula as AstraZeneca. Covaxin and Covishield were two major vaccines administered during Corona in India. After Covishield, now a study has come out regarding the side effects of Covaxin. A report published on SpringerLink states that adolescent girls and those who have had a history of allergies are at a higher risk of AESI after taking Covaxin. In one study, some type of reactions (AESIs) were seen in one-third of participants, according to a report published on SpringerLink. According to the report, researchers found that adolescent girls and people who have previously had allergies are at a higher risk of AESI after taking Covaxin. The study, conducted by Shankha Shubhra Chakraborty and her team at Banaras Hindu University, reported that most AESIs persisted during the one-year follow-up included in the study.
Of the 1,024 study participants, 635 adolescents and 291 adults were contacted during a 1-year follow-up. The study reported that upper respiratory tract infections were reported in 304 (47.9%) adolescents and 124 (42.6%) adults. The study also found that 4.6% of female participants had menstrual problems. Eye problems were seen in 2.7% of participants and thyroid deficiency was found in 0.6%. Apart from this, the people involved in the study also had to face this problem.
In teenagers:
➤ Skin and leather related problems (10.5%)
➤ General physical problems (10.2%)
➤ Nervous system disorders(4.7%)
In adults:
➤ General physical problems (8.9%)
➤ Muscle and bone disorders (5.8%)
➤ Nervous system disorders (5.5%)
Serious side effects (1%) included stroke in 0.3% and Guillain-Barré syndrome in 0.1%. According to the study, teenagers, women and people who have had allergies in the past are at a higher risk of developing AESI. The study also found that adults who had co-morbidities had more than double the risk of developing and sustaining AESI. The side effects after taking Covaxin were different from the side effects of other Covid-19 vaccines. Also, differences in these side effects were seen between adolescents and adults.
