Dear Readers,

Since JHPOR was established in 2012 we completed 19 Issues, always following the peer-review process. Currently, the work on the 20th Issue continues, and we are grateful for your continuous interest in publishing your research at JHPOR.

The scope of the Journal is focused on publications related to health policies, outcomes research and also on issues related to e.g. market access, quality of life or RWE in general. However, as the world is facing an unprecedented coronavirus pandemic, and we have observed the growing interest in vaccination topic, the JHPOR Editors Board agreed to issue a Call for Papers for a special collection of articles broadly dedicated to Vaccines with the aim to finalize the publication of the Special Issue by December 2022.

The Special Vaccines Issue has a focus on access issues, outcomes research, safety data analysis, epidemiology, and quality of life, and we believe that with the Special Issue we create an excellent opportunity to contribute with new evidence to aspects not yet addressed in relation to vaccines and to exchange different perspectives.

We encourage you to contribute to JHPOR, and we wish you many interesting readings.
