Are you still wearing your mask? Do they really work? Do you still have to wear one after getting the vaccine?

We all want to get rid of these masks. So, do they really help? Sanja IIic, OSU Associate Professor and food safety state specialist, did some research with Case Western Reserve University to see if mask wearing made a difference. IIic said the research was done to “demonstrate the droplet transmission and serve as an educational tool on how the viruses are transmitted and how we can prevent them in the community.”
They tested single-layer and double-layer masks made of different materials.
- Most effective masks – double-layer cotton, which was similar in effectiveness to surgical masks
- Least effective – single layered polyester masks
These experiments showed that wearing a face mask is an effective way to prevent the transmission of droplets. But, masks need to be worn correctly to be effective. Masks must:
- Completely cover the nose and mouth
- Fit snuggly against the sides of your face without gaps
- Be two or more layers of washable, breathable fabric
- Ideally have a nose wire to prevent air from leaking out of the top of the mask
Masks help people not to touch their nose or mouth, limiting the spread of the virus. But it is also important to follow social distancing guidelines of staying six feet apart, so droplet transmission is less likely if someone sneezes or coughs. Be sure to wash your masks after use and wash your hands before and after putting on or removing a mask.
Do you need to wear a mask if you have had the vaccine? Yes, experts recommend you wear a mask after you have had the vaccine.
- The pandemic is not controlled until around 50%-70% of the population become immune due to the vaccine or having the virus.
- The vaccine was tested on preventing COVID-19 but not on whether a person could be a carrier of the virus.
Thus, to help keep everyone safe, please wear a mask and practice social distancing until many more people have been vaccinated. Please consider getting the vaccine as soon as you are eligible.
