There is no evidence that getting the vaccination against influenza will help against COVID-19. They are different viruses and the antibodies that protect us from one virus do not protect us against the other. You could, however, be infected with both viruses at the same time, and getting the vaccination against influenza will reduce your likelihood of getting the flu and being sick from two viruses at the same time.
Similarly, vaccines such as pneumococcal vaccine and Haemophilus influenza type B (Hib) vaccine, do not provide protection against the new coronavirus. The term pneumonia means any lung inflammation caused by a bacterial or viral infection.
Although these vaccines are not effective against COVID-19, vaccination against respiratory illnesses is highly recommended to protect your health.
