The H1N1 flu – which is more popularly known as the swine flu – has become widespread in the late 2008. Although the symptoms are usually not very serious, the flu can sometimes be fatal. As a result, there is a growing need for a vaccine that will help fight against the H1N1 virus.
However, the vaccines – like all other flu vaccines – are made from eggs. So, people who are allergic to eggs are very likely to be allergic to these vaccines. The allergic reactions also occur in people who are not hypersensitive to eggs. All these people should not use swine flu vaccines.
Apart from allergic reactions, a few people also suffer from irritation of the skin. In this case, the area where the flu shot is taken swells up and becomes red. Since the flu shot is usually taken on the arm, it becomes painful for the people to move their arms. A great percentage of the vaccine users also suffer from fatigue and headache. In addition, the vaccine has also caused mild fever in many people.
After reading about so many side effects of the vaccine, many people may become reluctant to get flu shots. However, they must do a risk-benefit analysis. Although there are a few risks – such as allergic reactions associated with using the vaccine, the benefit – prevention of the deadly swine flu virus – is much higher. As a result, most people are advised to get their swine flu vaccines – unless they are extremely allergic to these.
