ABSTRACT
In Spain, the vaccination program began in a context of high transmission and low availability of vaccines. The objective of this article is to review the vaccination program against COVID-19 in Europe (3/03/2022) and assess the obstacles, challenges and opportunities posed by the control of this disease. Five vaccines are currently available in Europe: two based on mRNA technology (Comirnaty® and Spikevax®); two based on a non-replicative vector (Vaxzevria® and Janssen); and another based on subunit S (Novavax®). Health authorities have developed comprehensive vaccination strategies prioritizing the prevention of hospitalizations and deaths. In January 2022, 90% of the population was exceeded with full vaccination and 95% coverage in people over 50 years of age. The new challenge is to achieve similar coverage in the rest of the age groups. Vaccination in children and adolescents has become a priority due to the educational and social implications derived from COVID-19 in this population. Communication strategies must be renewed and access barriers eliminated to achieve good coverage. In Spain, studies have been published that find a high effectiveness of vaccination. The main strategy for controlling the pandemic and recovering social activity is the vaccination, but everything indicates that very high levels of vaccination coverage will be necessary and to follow with the non-pharmaceutical measures. In a globalized world, COVID-19 control will only be achieved with a coordinated global strategy and technical and economic support for the vaccination strategy in resource-poor countries.
