Dr. Cameron Wolfe, a Duke University infectious disease expert, looks at COVID-19 vaccine booster shots and some key questions to be considered.
A new Ipsos survey shows that a majority of adults in 13 countries believe first doses should be the priority, although most would get a COVID-19 vaccine booster shot if offered.
The pandemic could affect humanity for years to come, so a universal vaccine for every current and future variant would be a significant breakthrough.
The WHO has identified a new 'variant of interest' called the Mu variant, which was first discovered in January 2021 and has been in about 39 countries.
Some countries, such as Israel, are already rolling out a third booster shot to provide extra immunity to the most vulnerable members of their population.

Experts point to a more fundamental right to be protected from the disease, particularly as it continues to spread primarily among the unvaccinated.
COVID-19 variants threaten to undermine global vaccine programmes unless we accelerate the pace of delivery and rise to the challenge of global deployment.
The vaccine effort has raised awareness and sparked greater understanding of healthcare inequities, which will be valuable tools to face new healthcare challenges.
A resurgence of COVID-19 cases and lagging vaccination progress are holding many countries back. But the World Bank expects the global economy to grow by 5.6% in 2021.
The economic impacts of COVID-19 may last until 2024 in low-income countries because of the lag in vaccination, with only about 1% of people being vaccinated.
Many South African people are still reluctant to accept the COVID-19 vaccine due to misinformation; this could make it difficult to control the virus.
Operation Warp Speed (OWS) showed how successful public/private collaboration can be in building a mass vaccination program that could also work globally.
The WHO is urging people to wear masks again, even if they're vaccinated. An infectious diseases expert explains whether its time for the US to mask up.
BioNTech plans to start clinical testing by the end of 2022 for a new malaria vaccine, which aims to make the parasite visible and attackable when it enters the body.
