Flu Jabs: Your questions answered
1 Apr 2022
The best form of protection from the virus is through the flu vaccine. We understand, however, that decisions around getting vaccinated can be complicated for some. In the climate of disinformation on topics such as vaccines, we thought it would be a great time to share some insights, answering your commonly asked questions. Continue reading to help set your mind at ease about this year’s flu jab.
How does the flu vaccine work?
The flu jab uses a deactivated or weakened strain of an influenza virus which your body learns and identifies as an invader to your immune system to fight away. Using a deactivated or weakened strain causes your immune system to develop antibodies which will help detect and fight that flu strain off the next time it enters your system (Centers for Disease Control and Prevention, 2021).
Is the flu jab live?
No. The influenza vaccine we use in New Zealand does not contain any live viruses. Therefore, you cannot get Influenza directly from receiving the vaccine. The vaccine also contains no blood products.
How long does a flu jab last?
The flu vaccine is effective from six months to a year. Influenza regularly mutates, so that’s why you need to get the flu vaccine each year if you want to maintain protection from the virus.
Is the flu jab worth having?
Yes, it definitely is, especially for this year.
When we look at the pattern of Influenza infection from overseas over the European winter, we can predict that we will most likely have a higher incidence of Influenza throughout New Zealand this year. Due to the closed border, lockdowns and other COVID-19 precautions over the last two years, we have had a very low incidence of Influenza. As a result of low exposure rates, we as a population will have a lower-than-normal immunity to Influenza.
The best form of protection against the flu is through the vaccine.
Is the flu jab safe in pregnancy?
Yes. Research has shown the flu vaccine is safe for pregnant people and is strongly recommended (The Immunisation Advisory Centre, Kāhore he rā). Pregnant people may experience complications with Influenza, more so than non-pregnant people; therefore, it is strongly encouraged for pregnant people to get protected with the flu jab (Sandra Ponen, 2022).
Talk to your GP about possible risks and whether the flu jab is suitable for you during your pregnancy.
Flu jab and breastfeeding
Yes. The flu vaccine is safe for breastfeeding people. In fact, the flu vaccine helps the immune system develop antibodies that are then passed on to the infant (Centers for Disease Control and Prevention , 2021).
Talk to your GP for more information about receiving the flu vaccine while breastfeeding to ease your mind on whether it is right for you during this time.
Can the flu jab make you tired?
Yes. One of the common side effects of the flu jab is fatigue. This side effect is common and not anything to worry too much about. The flu vaccine uses energy as your body gears up its natural defences against the flu. This symptom should last no longer than 48 hours after receiving the jab.
Consult your GP if you have concerns about any of the symptoms experienced following the flu jab.
Can flu jab increase blood pressure?
There is no evidence that the influenza vaccination increases blood pressure, however for people who have hypertension or underlying cardiac conditions, getting the flu can elevate the risk of significant health issues. The stress that Influenza places on the body can increase blood pressure and the risk of heart attacks and strokes (Heart Foundation, 2021).
Can you have the flu jab if you’ve had the COVID booster?
Yes, you can. The COVID-19 vaccine only protects you from COVID-19; therefore, you will still need the flu vaccine in order to be protected against Influenza. You do not need to wait a certain period between each vaccine as they can be taken at the same time.
Do you need the flu jab if you’ve already had the flu?
Yes. The flu virus often mutates; therefore, it is essential to get protected from other potential strains circulating in the population. You will have developed antibodies for the virus you were recently affected by; however, you won’t have protection against other mutations that may be going around.
