Which vaccine would you choose

If you had the choice and not just choosing the fist one on the market.
Granted many people do not want any vaccine.
Top 5 listed below.

I have very limited knowledge on this subject but thinking the Johnson & Johnson vaccine may be the best. It may only need one shot and may only need to be kept at refrigerated temperatures.

Two of the vaccine candidates (from Johnson & Johnson/Janssen Pharmaceuticals and AstraZeneca/University of Oxford) use something called an adenovirus. What is that and why is it used?
Adenoviruses are viruses that can cause the common cold. We as humans have them, monkeys have them, as do other animals. For years, people have been using these viruses to deliver DNA, which are instructions for proteins. For the COVID-19 vaccine, researchers swap in a gene from SARS-CoV-2. When the vaccine is given to someone, the modified cold virus makes the SARS-CoV2 protein, which stimulates the immune response.

One of the vaccine candidates (from Merck, Sharpe & Dohme/International AIDS Vaccine Initiative) uses recombinant vesicular stomatitis virus. What is that?
Vesicular stomatitis virus is a virus that primarily infects livestock (cows, horse, pigs). Here, it is being used as a vector delivery system, much like the human or chimpanzee adenoviruses. The modified vesicular stomatitis virus delivers the instructions for the SARS-CoV-2 protein into cells. This recombinant candidate works really well against Ebola and has been proven in the field; people developed immunity to Ebola pretty quickly after getting vaccine.

The final two vaccine candidates (from Moderna and BioNTech/Fosun Pharma/Pfizer) are mRNA vaccines. What are those?
First it helps to remember that DNA is the gene and RNA gives instructions for certain proteins. So an mRNA vaccine is the instructions for the SARS-CoV2 protein. Once inside the cell, the protein is made and that triggers the immune response. Just like the vector vaccines which use viruses to deliver the protein instructions, here you are delivering the instructions alone. It’s another way of getting the protein made inside of you.
