COVID-19 vaccine: I'm not sure what you mean by "near future". Even the most optimistic estimates are 8-10 months, and more likely 1-2 years away. Research will determine if it is safe and effective and is the main reason it will take that much time. The US Food and Drug Administration will not permit marketing before a vaccine has been demonstrated to be safe and effective.

Vaccine studies: Although there is on-going research - unfortunately even when rushed, it takes quite a while to get a vaccine developed, approved and made. There is some promising research coming out of the U.K. There need to be a number of steps before a vaccine can be marketed - these are safeguards.

This vaccine is safe: The COVID-19 vaccine development has been much faster compared to previous vaccines, enabled by new technology. But the testing/evaluation of effectiveness and safety has been done according to the usual very strict standards. Trials of COVID-19 vaccines have included more than 75,000 participants, so if if there were serious side effects we would know. These vaccines are safe and effective

No: Many (dozens) are in development but none are available for distribution to the public. We also don't have one for SARS,MERS, Ebola & many others.
A member asked:

Will the eventual COVID-19 vaccine need to be taken annually, or once every several years?

Unknown: No one knows yet. It is too early to tell whether a vaccine, once developed, will be a one-time vaccine, or need a booster after a certain number of years, or if it will be annually (like the flu vaccine). As more research is done, that , and experience once the vaccine is widely available, will let us know.

A 42-year-old female asked:

Is covid19 becoming more or less aggressive ? Will there be a wave two ? Will it be over without a need for a vaccine ?

COVID 19: COVID 19 doesn't appear to be leaving any time soon. The anticipated second wave may just be the first wave continuing on without taking a break. The strain of COVID 19 from Europe appears to be more contagious (but not more deadly) than that from Asia. There are also concern that the dominant COVID 19 virus strain in Arizona has mutated & is more contagious.

As of today...: ... not yet, but many companies are working on it. It's more complex than can be explained in this answer, and mutations of the virus will throw more uncertainty into the mix.

A 60-year-old male asked:

Hi doctors! If God Willing there is a vaccine for covid, how will people know if and when and that it is safe to be near other people either without masks or with masks? When could people be in closer contact with each other and still feel safe?

Hard to speculate: I suppose when the regional covid-19 activity wanes to a sporadic level & hospitalizations drop off there would be less fear in the population. When or if that will occur is hard to predict. The emergence of improved early identification & treatments along with a drop in case fatality rate will also help. Feeling safe is a personal issue that varies with the individual. At some point we will adapt
