Dear Colleagues,

In 2022, Rīga Stradiņš University (RSU) for the first time organized a conference on vaccines and vaccination. These issues became critically important during SARS-CoV-2 pandemics. The pandemics put in focus a paraply of issues related to vaccine research and development, including principles of mass vaccination, vaccination complience and hesitance, acceptance of new vaccine modalities, preclinical/animal models for testing vaccine safety and efficacy and many more.

RSU organized international conference 'Vaccines and Vaccination During and Post Covid Pandemics / VAC&VAC 2022' on 7–9 December 2022 to address these important issues. The conference was held online on the Zoom platform provided by RSU, and united nearly 150 participants: 71 from Latvia, 7 from Sweden, 7 from Italy, 6 from USA, 4 from Republic of Korea, 3 from South Africa, 3 from the Netherlands, and also researchers from China, India, Tanzania, Denmark, Germany, Lithuania and San Marino. Participation in the conference was free.

The conference covered the progress in the development of vaccines achieved since the start of SARS-CoV-2 pandemics. It had sessions on COVID-19, epidemiology of Human Papilloma Virus (HPV) infection, HPV and cancer vaccines, progress in the development of vaccines against HIV-1 and other new and re-emerging microbial threats, novel vaccine formulations, adjuvants and careers, as well as populational aspects of vaccination. The topics were introduced by plenary lectures of renowned scientists from leading research institutions in USA, South Korea, South Africa, Italy, Sweden, Denmark, the Netherlands, China and Latvia, followed by oral presentations of original data, totally 32. 

All participants of the conference are invited to submit their studies to Vaccines | Special Issue: Pandemics-Born Revolution in the Preclinical and Clinical Trials of Microbial Vaccines (mdpi.com). Accepted submissions of conference participants get 20 % reduction of processing charges. If you are interested to submit, please, send an email to Organizing Committee with suggested submission type, title, tentative abstract, and timeline when manuscript can be ready. Deadline for manuscript submissions: 31 August 2023.

Abstracts

Abstract Submission

Registered participants of VAC&VAC 2022 conference submitted the abstracts that shaped conference program. Abstract submission closed November 28, 2022. Submissions were open in the sessions: (1) Covid-19 pandemics & vaccines; (2) Development of HIV-1 vaccines; (3) HPV infection & HPV vaccination; (4) Cancer vaccines; (5) Facing new and re-emerging threats; (6) Novel vaccine vehicles, adjuvants and carriers. Totally Organizing Committee received 35 abstracts including 6 for plenary lectures.   

Evaluation & Publication

All submitted abstracts were reviewed by the Reviewer Board. Decision on the acceptance and presentation form was communicated to the registered participants by email on 30 November 2022.

Abstracts were compiled into an Abstract book. The organising committee negotiates the possibility of publishing the abstract book with no additional charges to conference participants, alternatively, publish a conference report reviewing all presented studies in VACCINES (MDPI).

 Conference participants have also the possibility to submit manuscripts describing their experimental studies, short communications, reviews, opinions, comments to the special issue of VACCINES covering this conference Vaccines | Special Issue: Pandemics-Born Revolution in the Preclinical and Clinical Trials of Microbial Vaccines (mdpi.com), with reduced processing fee.

Early Career Researchers Contest

Organizing committe organized a contest of participants aged 36 or less. Presentations of early career researchers were assessed by independent board of five reviewers consisting or one professor, one associated professor, two senior researchers, and one PhD student. Presentations were assessed be series of criteria and winners established based on total ranks. 

Winners of the early career researcher contest are:

  • Massimiliano Bissa (Animal Models and Retroviral Vaccines Section, National Cancer Institute, Bethesda, Maryland, USA) – 1st prize, 
  • Andrea Cerasuolo (Istituto Nazionale Tumori IRCCS Fond. Pascale, Naples, Italy) – 2nd prize, 
  • Zane Lucāne and Yuliya Raukach, Rīga Stradiņš University, Riga – shared 3rd prize.

Winners will recieve monetary awards in amount of 300 euro, 150 euro and 75 euro, respectively, and 1st and 2nd place winners, also vouchers for free publication in special issue of VACCINES covering the conference.
