Flu infections caused by the members of Influenza virus (RNA virus) have high mutation rates as the RNA-dependent RNA polymerase involved in virus replication lacks proofreading activity. This incorporates novel mutations in surface glycoproteins such as hemagglutinin (HA) and other virus proteins. These new mutations get positively selected as the pre-existing antibodies cannot recognise these altered proteins anymore. Hence, comes the need for new versions of flu vaccines every year.

The seasonal flu vaccines have been found to be safe and clinically accepted. The only comlication that are found to arise due to these vaccinations are pain, redness and swelling at the site of injection.

The flu-severity is highest in younger and elderly age groups. Even if we do not belong to that age group, we must get vaccinated in order to prevent the chance of getting infected and spread the virus to the individuals of those age groups.

Thus, due to the effectiveness, lower-risk factor of the vaccination and overall health benefits of the community,we must get seasonally vaccinated for flu.

Each year in the US, millions of people become ill and thousands die from eating food contaminated with bacteria. Controlling growth of microorganisms on food is a particular challenge, and over the course of many centuries various methods have been developed for controlling microorganisms in food. Some of these include preservation by irradiation, drying, freezing, canning, and salting. Preservation by salting is based on the principles of osmosis. One example of this is the preservation of ham by applying large...
