ravenhome777,
Yes, you can still get COVID after vaccination. Vaccination never has meant you can't get infected with a pathogen. For example, vaccination against COVID or the flu won't stop those viruses from getting into your mouth, nose, eyes if you come in contact with them.
It's important to go over, in layman's terms, cause I'm a layman lol, what vaccination does. It elicits an immune response to generate protections against a pathogen that exists in nature. Once vaccinated the body produces antibodies. The body also produces T-cells and B-cells. The antibodies that you would get in the immediate aftermath of vaccination or infections are called neutralizing antibodies. This means you actively have these proteins circulating. If you were to come into contact with COVID at this time you might hardly feel it as the circulating antibodies when be in the blood already to swallow them up. However, these antibodies contract after a period of time. With COVID, from my understanding, they contract quite significantly after 3 - 4 months. However, the memory cells, like B-cells, last much longer. Think of these as your conductors. When you become exposed to COVID, or whatever disease, these memory cells instruct the body to make antibodies again. They already know what COVID looks like. They have "memory" and can get to work right away. The unfortunate part of that is it can take a day or two for the body to really ramp up and make enough antibodies to overtake the replicating virus. So you might feel sick for a day or two. Compare this to having no immune exposure to the virus and having your immune system having to start from scratch.
I agree with you that people are pretty made up in their minds about
this subject at this point. However, if you can convince your parents to get vaccinated you could possibly save their lives. At 78 and 80 they are at high risk of a serious illness, hospitalization, and even death. As we age our immune systems become less and less effective. It's critically important that elderly people are vaccinated against COVID. Some people around that age are still dying despite being vaxxed with 2 doses and sometimes even 3. That's why it seems like vaccinations are being handed out like candy to the elderly.
I'm not aware of Novavax being any better or worse than the mRNA vaccines. They use different delivery systems. Pfizer and Moderna use mRNA. Novavax uses a lab made spike protein without the genetic material. They have different delivery systems but both use the spike protein to elicit an immune response.
