Covaxin, Covishield vaccines FAQs

Bharat Biotech on Monday released a ‘fact sheet’, which contains details of the risks and benefits of its Coronavirus. The company reinstated that the efficacy of the vaccine is yet to be determined as its Phase 3 trial is still underway.

Earlier this month, SII had also released a similar document consisting of FAQs. Serum Institute said that the beneficiaries should make certain health issues clear to the doctor before taking the vaccine.

The companies were given approval for the restricted use of their vaccines in an emergency situation and released their vaccines last Saturday, January 16, 2021. Till 5 pm on Monday, 3.81 lakh people had been administered the vaccines. There were 580 adverse events. While two people died after being injected with the vaccine, the Union Health Ministry says the cases aren’t linked with the vaccination.

Bharat Biotech has said that it is not advisable to take Covaxin under following cases:

  • Have any allergies
  • Have fever
  • Have a bleeding disorder or are on any blood thinners
  • Are immunocompromised or taking medicine that affects your immune system
  • Are pregnant
  • Are breastfeeding
  • Have received another COVID-19 vaccine.
  • Any other serious health-related issues, as determined by the vaccinator.

The company has specified that people who are pregnant or breastfeeding shouldn’t take the vaccine as its effects haven’t been studied on pregnant people and nursing parents.

It has also said that there is “no scientific information yet available of the appropriateness of use of Covaxin along with other vaccines.”

Covaxin is injected into the deltoid muscle of the upper arm and is expected to generate immunity after two doses which are four weeks apart. Bharat Biotech has said that there is no chance of getting COVID-19 due to Covaxin.
