This project involves the development of a COVID-19 vaccination campaign with the aim of informing people over 18 years of age who have completed 3 months of their second dose to protect themselves with the booster dose. It was decided to combine two elements that are well known to a young person, the shape of a battery and that of a vaccine, thus achieving harmony with the concept of the campaign, which is to top up your personal battery level with the vaccine. Finally, emojis of various faces were added, so that the public can identify with them.
