Introduction

There is a flu outbreak every year and there is a new flu vaccine being introduced every year. The reason is this - the flu virus changes or mutate a little every year, building it impossible to create a vaccine that is permanently good year after year. Instead, each year a new flu vaccine needs to be introduced that is successful for that particular year.

According to data from Center for Disease Control, Atlanta, USA, this months flu outbreak that is happening in USA is mainly due to flu virus of the Fujian variant (79%) and the Panama variant (21%).

So, is flu vaccine good?

No vaccine is 100% effective. For the flu vaccine to be efficient for this outbreak, ideally the vaccine needs to contain both the Fujian and Panama variants. Unfortunately, the present available flu vaccine isnt.

However, that is not to say that the vaccine is totally useless. It would still afford a certain degree of protection as there is cross-immunity. In other words, the immunity that you get from one particular variant provides you with partial protection against other variants. Some protection is better than no protection, particularly for the immuno-compromised, such as:

-those above 65 years old
-children below 2
-many people undergoing treatment for terminal illness
-those travelling to affected areas in USA

Some Common Sense Approaches

As in all outbreaks, the flu vaccine is currently difficult to come by as demands outstripped supply. Thus, if you think you are likely to be affected, try to get the vaccine as soon as you can. It takes two weeks after the injection for the antibodies to be produced and for you to be protected. So, if youre going to USA in two weeks time, go for your shot now!

Besides the vaccine, there are some simple preventive measures you can take.

1. Wash your hands every measure you touch something that others have touched. Flu is air-borne and droplets containing the virus can deposit on any thing you touched. Carry wipes with you, for that purpose, when away from home.

2. Boost up your immunity by eating a proper and balanced diet, containing lots of vegetables and fruits. Go for your daily walks or exercise, even if its only for 10-15 minutes. Drink plenty of water. Take vitamins and mineral supplements if you think youre deficient in those.

3. Avoid crowded places. Being in a crowded place adds your risk of being exposed to someone with the flu.

4. If youre having the flu, stop it from spreading by staying at home or covering your nose and mouth when you sneeze.
