The CRISPR Journal is a peer-reviewed scientific journal published every three months by Mary Ann Liebert. It covers research on all aspects of CRISPR research, including its uses in synthetic biology and genome editing .
The impact factor relates to a specific time period; it is possible to calculate it for any desired period. For example, the JCR also includes a five-year impact factor, which is calculated by dividing the number of citations to the journal in a given year by the number of articles published in that journal in the previous five years.

Human-to-human transmission of SARS‑CoV‑2 was confirmed on 20 January 2020 during the COVID-19 pandemic. [16] [39] [40] [41] Transmission was initially assumed to occur primarily via respiratory droplets from coughs and sneezes within a range of about 1.8 metres (6 ft).
The timeline of the COVID-19 pandemic lists the articles containing the chronology and epidemiology of SARS-CoV-2, [1] the virus that causes the coronavirus disease 2019 and is responsible for the COVID-19 pandemic. The first human cases of COVID-19 occurred in Wuhan, People's Republic of China, on or about 17 November 2019. [2]
CRISPR repeats typically range in size from 28 to 37 base pairs (bps), though there can be as few as 23 bp and as many as 55 bp. [80] Some show dyad symmetry, implying the formation of a secondary structure such as a stem-loop ('hairpin') in the RNA, while others are designed to be unstructured.
All RMPs for COVID‑19 vaccines will be published on the EMA's website. [136] The EMA published guidance for developers of potential COVID‑19 vaccines on the clinical evidence to include in marketing authorization applications. [137] In November 2020, the CHMP started a rolling review of the Moderna vaccine for COVID‑19 known as mRNA-1273 ...
The history of coronaviruses is an account of the discovery of the diseases caused by coronaviruses and the diseases they cause. It starts with the first report of a new type of upper-respiratory tract disease among chickens in North Dakota, U.S., in 1931.
According to a June 2022 study, COVID‑19 vaccines prevented an additional 14.4 to 19.8 million deaths in 185 countries and territories from 8 December 2020 to 8 December 2021. [ 405 ] On 10 December 2021, the UK Health Security Agency reported that early data indicated a 20- to 40-fold reduction in neutralizing activity for Omicron by sera ...
