Good morning everyone - I think that what we need to keep in mind is that these vaccines are not the be-all or end-all vaccines for this virus. They most likely will be tweaked several times, or maybe a new kind of vaccine against COVID-19 and its variants will be discovered. But! But! This is what we have now and to me as a lung cancer survivor, it's a fine beginning!

Dr. Fauci explained why it's important, imperative to get vaccinated.:

"Vaccines can protect against serious diseases, including hospitalization and death," Fauci said. "They could also keep variants from becoming more dominant."

"Viruses cannot mutate if they don't replicate. And if you stop their replication by vaccinating widely and not giving the virus an open playing field to continue to respond to the pressures that you put on it, you will not get mutations," Fauci said.

"You need to get vaccinated when it becomes available as quickly and as expeditiously as possible throughout the country."

Experts remain concerned about the spread of the variants. "Right now we are in an absolute race against time with these variants, with trying to get people vaccinated before they spread too much across our country," said emergency physician Dr. Megan Ranney, director of the Brown-Lifespan Center for Digital Health in Rhode Island. "It means that just going to the grocery store, to school, or to work could become more dangerous. We have an already overtaxed and exhausted health care system."

Presently there are three variants in the US. We do need to stop them and getting vaccinated will help stop it. Being tested for immunity is a great idea, but will the test include the variants? And will your immune system be able to fight it all?
