Since March, over 400 US colleges and universities have announced students get Covid-19 vaccinations, ahead of the Autumn semester but those who have been inoculated with India's indigenous Covaxin or the Russian-made Sputnik V are being asked to re-vaccinate as these vaccines have not yet been approved by the World Health Organization (WHO).
Rukmini Callimachi reports in The New York Times that Milloni Doshi, a 25-year-old student from India, who is due to start her master's degree this fall at Columbia University's School of International and Public Affairs, has been administered two doses of Covaxin. Now, Columbia has told her that she will need to be revaccinated with a different vaccine once she arrives on campus.
Campuses are proposing different measures, out of which the more complicated scenario is if students received a vaccine that has not been approved by the WHO, like Sputnik or Covaxin. Many colleges are proposing that those students will need to be revaccinated, which presents both medical and logistical conundrums.
This is primarily because no data exists on whether combing vaccines from different companies is safe. "Since Covid-19 vaccines are not interchangeable, the safety and effectiveness of receiving two different Covid-19 vaccines have not been studied," said Kristen Nordlund, spokesperson for the Centers for Disease Control and Prevention (CDC).
