@curious2know as others have mentioned, the answer to your question is best answered by your doctor, so that she or he can give you advice relevant to your health status. As @astaingegerdm suggested, currently medical professionals and infectious disease specialists advise at this time get flu and pneumonia vaccines to help avoid getting other these illnesses and keep you as healthy as possible. Flu and pneumonia vaccines don't protect against COVID-19.

Here is some information that I found from the Government of British Columbia, Canada's website (https://immunizebc.ca/question-categories/pneumococcal-vaccines) that addresses your questions specifically.

EXCERPT
Question: Should I get the Prevnar 13 vaccine at this time of the situation of Covid-19 to prevent any serious infection?
Answer: Immunization with Prevnar® 13 vaccine may be considered. Discuss this vaccine with your health care provider.

Question: Is the Prevnar-13 Vaccine effective against Covid-19 pneumonia.
Answer: According to the World Health Organization:
"Vaccines against pneumonia, such as pneumococcal vaccine and Haemophilus influenza type B (Hib) vaccine, do not provide protection against the new coronavirus. The virus is so new and different that it needs its own vaccine. Researchers are trying to develop a vaccine against 2019-nCoV. Although these vaccines are not effective against 2019-nCoV, vaccination against respiratory illnesses is highly recommended to protect your health."

@curious2know, I'd be curious to hear what you find out from your physician.
