Do you mean safe for people or safe for the planet?  I am observing that research in basic science is progressing quickly, and many of the companies that make pharmaceutical products are well-funded.  I am noticing that so far there have not been any bad side effects reported from the vaccine.  I am also wondering if there will be ethical issues around how the vaccine is distributed.

No, we do not yet have an effective vaccine for Covid-19.  Many ongoing research projects are attempting to develop an effective vaccine.

What do you think of the covid situation?

I am observing that global businesses are learning to work in ways that depend less on face-to-face interactions, since much of the world is practicing social distancing.  There is also now a very high awareness of the need for everyone to wash their hands and avoid other kinds of contamination.  Is there anything else I should say?
