Can I Take Two Doses of Covishield and Covaxin for Safe Travel Abroad?

Vaccination Schedule and Travel Plans

When planning your travels, you might consider taking two doses of different vaccines, such as Covishield and Covaxin, for added protection. However, it's important to understand the implications and recommendations surrounding this approach. It's not without controversy, especially considering the differing effectiveness of these vaccines when administered in a staggered manner.

The Indian Council of Medical Research (ICMR) - National Institute of Epidemiology conducted studies on the efficacy of different vaccine schedules. According to senior author and Director of ICMR-NIE, Dr. Manoj Murhekar, the vaccine effectiveness was highest when two doses of both vaccines were separated by 6-8 weeks. This optimal interval was chosen based on sufficient data, but there weren't enough numbers to assess the efficacy of a 12-week interval.

In a conversation with The Indian Express, Dr. Murhekar emphasized the importance of staggered doses. He stated, 'The main point here is vaccines are effective. We do not really need a booster immediately as by June this year at least 60% of the country's population was infected with SARS-CoV2, and vaccination would have served as a boost to the immune system.'

Alternatives for Travelers

For those urgently needing to travel abroad, there are several alternatives to consider:

Take Covishield: This vaccine requires a longer dosing interval, often around 6-8 weeks between doses. While this might be more challenging for immediate travel plans, it ensures a more prolonged period of protection. Await WHO's Approval for Covaxin: Consider waiting for the official approval from the World Health Organization (WHO) for Covaxin. This may take a few more months, but it ensures access to a fully-vetted and approved vaccine. - Stay Flexible: Be prepared to wait for the appropriate vaccination, as there are currently vaccine shortages. Rushing into an unprotected schedule could exacerbate the situation.

Is It Risky to Mix Vaccines?

Mixing vaccines, such as taking two doses of Covishield and Covaxin, is not recommended unless under specific medical advice. While it might seem like a viable option, the combination has not been thoroughly studied and could lead to unexpected outcomes, including diminished effectiveness or adverse reactions.

Dr. Murhekar warned, 'Mostly all the vaccines would be permitted for internal use, but international travel requires a clear vaccination certificate. If taken life-threatening risks, alternative options should be considered.' This statement emphasizes the need for durability, trust in the approved vaccine schedule, and the potential health risks associated with mixing vaccines.

Recommended Vaccination Schedule

For safe and effective travel, prioritize one of the below options:

Staggered Schedule: Aim for doses of Covishield or Covaxin with the recommended interval of 6-8 weeks. Single Vaccine: Whichever vaccine is available and approved for your region, complete the series as directed. Prepare for a Wait: If you must travel soon, choose Covishield and be prepared to wait an additional period to get the complete dosing regimen.

While the journey of global travel is undeniably challenging, adhering to the recommended vaccination schedules ensures not only your own safety but also contributes to the collective immunity needed to combat the virus effectively.

Conclusion

Traveling abroad is a significant commitment requiring proper preparation, including a fully vaccinated status. Mixing vaccines is neither advisable nor recommended. Instead, opt for the approved and recommended dosing schedules for Covishield, Covaxin, or any other vaccine approved in your region. This approach not only maximizes your protection but also helps in achieving herd immunity, ensuring a safer and smoother travel experience.
