Implementation and evaluation of the human papillomavirus (HPV) vaccination pilot for men who have sex with men (MSM), England, April 2016 to March 2017.

BACKGROUND: Opportunistic human papillomavirus (HPV) vaccination for men who have sex with men (MSM) was piloted in sexual health clinics (SHC) in England between 2016 and 2018. AIM: to evaluate the pilot's first year (April 2016-March 2017) in terms of feasibility, acceptability, uptake, impact and equity and interpret the outcome in the context of wide HPV vaccination policy. METHODS: Attendance and uptake data from routine SHC surveillance datasets and a cross-sectional survey administered to individuals receiving the vaccine were analysed. RESULTS: Among 18,875 eligible MSM, 8,580 (45.5%) were recorded as having received one HPV vaccine dose, decreasing slightly with increasing age, and uptake was higher in rural than urban areas. Survey results suggested that of those receiving the first dose of HPV vaccine, 8% were new attendees and that among those, less than 11% attended just to receive the vaccine. Of those having their first HPV vaccination, 95% indicated they would like to receive the next vaccine doses at the same clinic and 85% of patients reported accessing other services when visiting SHC for the first dose of vaccine. CONCLUSION: An opportunistic HPV vaccination programme for MSM can be delivered in an acceptable and, as far as can be evaluated, equitable manner, without major disruption to SHC and HIV clinics.

The Effect of Nucleic Acid Extraction Platforms and Sample Storage on the Integrity of Viral RNA for Use in Whole Genome Sequencing.

Extraction of viral RNA and the storage of sample material are extremely important factors in the detection and whole genome sequencing (WGS) of viral pathogens. Although PCR-based detection methods focus on small amplicons, viral WGS applications require RNA of high quality and integrity for adequate sequence coverage and depth. This study examined the fitness of one manual and four automated RNA extraction platforms commonly used in diagnostic laboratories for use in metagenomic sequencing, how the practice of storing sample material in Qiagen buffer AVL before extraction affected the integrity of viral RNA and its suitability for use in amplicon-based WGS methods, and how the addition of Triton X-100 to buffer AVL affected the capability of the extraction platforms and the integrity of viral RNA in stored samples. This study found that the EZ1 platform gave the best performance of the automated platforms and gave comparable results to the frequently used manual Qiagen extraction protocol when extracted viral RNA was used in metagenomics sequencing. To maintain high levels of viral RNA integrity suitable for amplicon-based WGS, nucleic acid should be extracted from samples immediately, because even short storage periods in buffer AVL have a severe effect on integrity, and the addition of Triton X-100 had little effect on the quality of viral material for WGS.
