I wanted to make sense of the Vaccines, because to me, it was a confusing arena. Especially since my brain is caught up with the heavy stupor or steriods and blood anti-coagulants and antibiotics. So here is what I have drafted, from sources online. If I have made any mistakes, please feel to let me know, in the comments section.

| India: | Available | ? | Available | ? | No | No |
- Even if you have comorbidities – vaccinate!
- If after first dose you have anaphylactic problems. Don’t take the second dose
- If you are on Steroids, don’t take.
- Pregnant lactating woman should be vaccinated with Pfizer, moderna, no side effects.
- Vaccines working against all strains. But with two doses.
- If you get infected after the first dose – infection will be mild
- WHO states you can wait for 6 months between first and second dose of vaccination.
- 80% efficacy after first dose, for that duration, if shortage in vaccination. Do not panic.
- If you have been infected by COVID the combination of antibodies (Natural immunity) and vaccine is the best protection – and you may just need one dose of vaccination.
- Vaccines don’t work instantly.
- Astra is best in efficacy long term
- Even if u do vaccinate you may get COVID- it’s 94-95 % effective.
- If you have been infected with COVID-19, wait for 6 months to get vaccinated.
- Ask the Government to bring in mRNA vaccines!
