Covid vaccine Letter of the day by Bernard Jarman, Stroud. The new Covid-19 vaccines are now becoming available for those wishing to take them. They have been produced at break-neck speed and although they have undergone a certain amount of testing, not everyone is convinced of their safety. Before being vaccinated it is therefore wise to have as much information about them as possible. As with every product which is advertised on the market objective information will not be found from those promoting it. This means in the case of these vaccines that the information put out by the vaccine companies, ministers with shares in vaccine companies, medical experts sponsored by vaccine companies and branches of the media receiving grants from these same companies cannot be relied on to provide a full and independent risk analysis of the products.
