Force line break every x amount of characters but preserve words from being clipped

I am getting back a long string of words and need to add some line breaks to make it readable.

Using the method below I am able to add breaks, but it cuts off words in various places.

While much of the world still is focusing on COVID-19, the potential for another serious influenza season can’t be ignored, and the strain on the health care system of 2 epidemics could be severe.1 As the SARS-CoV-2 virus continues to spread across the country, the 2020-2021 influenza season will be particularly challenging.1 Recent influenza seasons have been particularly serious: 2017-2018 was one of the deadliest in decades, with an estimated 61,000 deaths, and 2018-2019 was one of the longest flu seasons, lasting 21 weeks.2 The 2019-2020 influenza season was on a trajectory to be particularly severe, especially for children because of a high prevalence of influenza B cases.3 However, the season ended 5 to 6 weeks earlier than anticipated after control measures were put in place to prevent COVID-194; even with the shortened season, the Centers for Disease Control and Prevention (CDC) estimated 34,157 deaths, which was on par with the number of cases from 2018-2019.2,3  Although influenza viruses cannot be controlled directly, there are several measures that can be taken to help mitigate the severity of the influenza season.

var newStr = str.replace(/(.{1,500})/g, '$1<br/><br/>')

Lookahead for a space or the end of the string after the end of the pattern:
