Currently there are two vaccines in this country for use against COVID-19 (SARS-CoV-2). These are based on the SARS-CoV-1, MERS-CoV (Middle East respiratory syndrome coronavirus) and Ebola vaccine (2019). The target for these vaccines is the surface of the spike protein common to all. The vaccines enable us to produce antibodies that cover the spike protein so as to stop the virus from entering our cell.
Note: a virus is not a life form, it is not alive. It is nothing more than genetic material (DNA or RNA) surrounded by a protein shell. In order for the virus to enter a cell it needs a way to connect with the cell, and for COVID-19, that is the spike protein. This acts like a magnet to attach to the cell. When this happens, the cell thinks it is friendly and brings it inside the cell where the protein shell disintegrates and the RNA floats freely to do bad things.
The vaccine enables our body to produce antibodies that cover the spike protein and inactivate the “magnet”, so the virus does not attach to the cell and prevents illness.
This is not really a “new” vaccine but a modification of previous ones. It appears to be ~ 95% effective.
The Pfizer vaccine is indicated for individuals aged 16 yrs. or older; the second dose is given 21 days later.
The Moderna vaccine is for individuals aged18 yrs. or older; the second dose is given 28 days later. For both, the CDC favors the vaccines even in individual who had COVID-19 and is not contraindicated in pregnancy. Both vaccines appear to exert full effect 2 weeks after the second vaccine.

If COVID-19 is not really spread by sneezing or coughing, then why the mask? The reason is simple. When one coughs and covers his/her mouth with a hand, or sneezes into the hand or blows his/her nose with the hand holding a tissue, there is a huge inoculum now on the surface of that hand. That inoculum can easily be transferred to a doorknob, a pen, paper, shopping cart handle, etc. After you touch any of these items, if you now touch your mouth, nose, rub your eyes- bingo you just transferred the inoculum to your mucus membrane, and you are now infected. The mask is a barrier to protect you, so please use it. Also, it is strongly recommended to use hand sanitizers. Hand sanitizers have been shown to be 99.9% effective within 6 seconds! This serves as another layer of protection.
