<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" ALIGN="center"><B>Supplement dated August&nbsp;27, 2020 to the Prospectus, </B></P>
<P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" ALIGN="center"><B>dated April&nbsp;29, 2020 </B></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">This supplement
amends certain information in the Prospectus dated April&nbsp;29, 2020, of BlackRock Health Sciences Trust (the &#147;Fund&#148;). Unless otherwise indicated, all other information included in the Prospectus that is not inconsistent with the
information set forth in this supplement remains unchanged. Capitalized terms not otherwise defined in this supplement have the same meanings as in the Prospectus. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Effective immediately, the following change is made to the Prospectus: </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>The section of the Prospectus entitled &#147;Item 8. Part II&#151;Description of the Fund&#151;Portfolio Contents and Techniques&#148; is amended to add
the following at the end of such section: </I></P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Environmental, Social and Governance (&#147;ESG&#148;) Integration </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Although the Fund does not seek to implement a specific ESG, impact or sustainability strategy, Fund management will consider ESG characteristics as part of
the investment process for actively managed funds such as the Fund. These considerations will vary depending on a fund&#146;s particular investment strategies and may include consideration of third-party research as well as consideration of
proprietary research of the Advisor across the ESG risks and opportunities regarding an issuer. Fund management will consider those ESG characteristics it deems relevant or additive when making investment decisions for the Fund. The ESG
characteristics utilized in the Fund&#146;s investment process are anticipated to evolve over time and one or more characteristics may not be relevant with respect to all issuers that are eligible for investment. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">ESG characteristics are not the sole considerations when making investment decisions for the Fund. Further, investors can differ in their views of what
constitutes positive or negative ESG characteristics. As a result, the Fund may invest in issuers that do not reflect the beliefs and values with respect to ESG of any particular investor. ESG considerations may affect the Fund&#146;s exposure to
certain companies or industries and the Fund may forego certain investment opportunities. While Fund management views ESG considerations as having the potential to contribute to the Fund&#146;s long-term performance, there is no guarantee that such
results will be achieved. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" ALIGN="center"><B>Investors should retain this supplement for future reference. </B></P>
