If an unvaccinated person is around a person vaccinated against COVID-19, they tend to feel dizzy and can also pass out.

There are no reported instances or evidence that unvaccinated people could feel dizzy and faint when they are around vaccinated people.

There are no reported instances or evidence that unvaccinated people could feel dizzy and faint when they are around vaccinated people. Studies have proven that COVID-19 vaccines are effective at keeping you from getting COVID-19. Getting a COVID-19 vaccine will also help keep you from getting seriously ill, even if you do get COVID-19. There's also evidence that getting vaccinated reduces the risk of developing asymptomatic infection and spreading the virus to others. In addition, there are no reports of unvaccinated people fainting or passing out by being near those vaccinated against COVID-19.

According to John Hopkins, fully vaccinated people have a relatively low risk of contracting COVID-19. It is unlikely that the virus can transfer from vaccinated to unvaccinated people. Moreover, the Center for Disease Control and Prevention (CDC) guidelines state that fully vaccinated people could continue normal activities without masks unless any governing law or workplace says otherwise. For example, in homeless shelters and correctional facilities, fully vaccinated people should continue to wear a well-fitting mask. Unvaccinated people should still take preventative precautions like social distancing and wearing masks.

According to Mayo Clinic, two weeks after receiving their second dosage of an mRNA vaccine, such as Pfizer-BioNTech or Moderna, or two weeks after receiving a single dose of the Janssen/Johnson and Johnson vaccine, persons are deemed fully immunized. The only exception is when a fully vaccinated person has any underlying medical condition or is taking immune-suppressing medicines.

Furthermore, other scientific studies and government agencies have quoted CDC guidelines, claiming that fully vaccinated people who do not use masks or are physically separated are likely at low risk.

According to World Health Organization (WHO), COVID-19 is typically transmitted by persons who have symptoms. Still, it can also happen right before they acquire symptoms if they are in close proximity (1 meter) to others for an extended period.

COVID-19 transmissibility from completely vaccinated to unvaccinated people is low. There have been no reports of fully vaccinated people getting dizzy or passing out when an unvaccinated person is around.

The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19, including symptoms, prevention, and available treatment, please refer to the World Health Organization or your national healthcare authority.
