The vaccination drive for the deadly virus which has taken the whole world by a shock has begun in India from the 16th of January and it has escalated in different phases starting from the age group 65+ and then slowly moving down to lower age groups. The Oxford-AstraZeneca has developed the Covishield and it is being manufactured by the Serum institute of India(SII). The Hyderabad-based Bharat Biotech International Ltd. in association with indian council of medical Research(ICMR) and the National institute of Virology(NIV) has developed the Covaxin.
The effectiveness of a vaccine is based on the efficacy rate. The efficacy rate is basically the percentage reduction in a disease in a group of people who have received a dose of the vaccine in the clinical trials. It is different from vaccine effectiveness. The Covishield gives us an efficacy of nearly 90%
The Covaxin gives us an efficacy of 81% (according to interim 3rd phase trials). The 2nd dose of the Covaxin is given 4-6 weeks after the first dose. The 2nd dose of the Covishield is given 12-16 weeks after the first dose. For both Covishield and Covaxin After getting vaccinated, you may detect pain at the site of injection. People may also experience side effects such as joint aches ,headache, and may be down with fever. These side effects do not continue for long and you are relieved within a day or two.
Both the vaccines are intramuscular vaccines.
What doctors have to say is that, people should not be skeptical of which vaccine to get and to get jabbed as soon as possible. They have said the priority should remain on getting vaccinated. People can surely make informed choices between the two vaccines (if and when they get a choice) taking into consideration the side-effects, such as fever, swelling, ache, etc.. Both the vaccines have almost equal effective rates, even if they don’t fully protect from COVID both Covaxin and Covishield are known to cut down the severity and mortality risk analogous with the infection. The vaccine availability may also depend state-to-state, so it is always better to get vaccinated as soon as possible.
