Children will be able to get a free flu vaccine from Friday in a move to reduce hospital admissions, RNZ reveals. Health Minister Andrew Little said the government was expanding access to the flu vaccine after noticing an increase in pre-schoolers hospitalised with the illness. Meanwhile, from Tuesday, a second Covid-19 booster dose will also be available to anyone over 50, and health, aged-care and disability-care workers over the age of 30, with a six-month gap between doses.
